Abstract

Planetengetriebe (1) mit einem Sonnenrad (3), mit drei oder mehr Planetenrädern (7), mit einem Hohlrad (39) und mit einem Planetenradträger (19), wobei der Antrieb über das Sonnenrad (3), der Abtrieb über das Hohlrad (39) oder den Planetenradträger erfolgt, wobei jedes Planetenrad (7) beidseitig in je einem Wälzlager (11) abgestützt ist und wobei der Planetenradträger (19) zwei axial beabstandete Lagerscheiben (20) und mindestens drei, die Lagerscheiben (20) verbindende Stege (23) aufweist. Jedes Wälzlager (11) ist als ein- oder mehrreihiges Zylinderrollenlager ausgeführt, jedes Planetenrad (7) weist eine biegeelastische, beidseitig axial über den Radkörper (8) des Planetenrades (7) vorstehende Achse (9) auf, und die Verbindung zwischen jedem Wälzlager (11) und der jeweiligen Achse (9) ist sphärisch beweglich ausgeführt.Planetary gear (1) with a sun gear (3), with three or more planet gears (7), with a ring gear (39) and with a planet carrier (19), wherein the drive via the sun gear (3), the output via the ring gear ( 39) or the planet carrier, wherein each planet (7) is supported on both sides in a rolling bearing (11) and wherein the planet (19) has two axially spaced bearing discs (20) and at least three, the bearing discs (20) connecting webs (23 ) having. Each rolling bearing (11) is designed as a single or multi-row cylindrical roller bearing, each planetary gear (7) has a flexurally elastic, on both sides axially on the wheel body (8) of the planetary gear (7) projecting axis (9), and the connection between each rolling bearing ( 11) and the respective axis (9) is designed to be spherically movable.
